Description

[Detailed Description of the Invention] This invention relates to a built-in fitting for attaching rods such as hanging fittings for various pipes installed under the floor of a building.

Conventionally, the installation of rods such as this type of hanging fittings to floor slabs was done by
It is common to embed a simple plate-shaped embedded metal fitting in the floor slab that has a female thread that engages with the male thread of the rod, and then attach the rod by screwing the male thread of the hanging metal rod to this embedded metal fitting. It was carried out in

Therefore, if the buried position of the plate-shaped embedding fitting shifts, or if the bending of the piping is not done according to the drawing, and the buried position shifts as a result, the installation position of the rod may be changed. Since I could not make any adjustments, I had no choice but to forcefully bend the rod to match the position of the pipe and hang the pipe.

This reduced the efficiency of piping construction, and the rods were forced to bend, causing problems such as cracks and damage to the floor slabs.

This idea was made in view of the above-mentioned circumstances, and its purpose is to easily adjust the mounting position of rods such as hanging fittings even if the embedded position of the embedded fittings is misaligned. The purpose of this invention is to provide an embedded metal fitting that allows for.

An embodiment of this invention will be described below with reference to FIGS. 1 and 2.

In the figure, reference numeral 1 denotes a bottomed hollow cylindrical casting-made embedded fitting body with an open bottom end, which has a threaded portion 2 on the inner circumferential surface of its peripheral wall 1a, and an anchor protrusion 3 on its bottom wall 1b. have.

This anchor protrusion 3 is provided with a female thread 3a in a cross direction into which an anchor bolt 4 is screwed.

Furthermore, the main body 1 has three fixing protrusions 5, which are equally distributed in the circumferential direction, and have nail holes 5a for fixing the main body 1 to the formwork 6 when embedding the main body 1 in a floor slab on the lower edge. .

Reference numeral 8 denotes a disc-shaped rod mounting plate made of cast iron having a long hole 8a extending in the radial direction, and has a threaded portion 9 on its outer periphery to be screwed into the threaded portion 2 of the main body 1.

The elongated hole 8a is sized so that a threaded portion 10a of a rod 10 in the form of a bolt with a head such as a hanging fitting can be slidably inserted thereinto. It is fixed to the rod mounting plate 8 by tightening a nut 12 through the rod.

Then, this embedded metal fitting body 1 is installed in the concrete of the floor slab)
To embed the body in A, first place the main body 1 at a predetermined position on the formwork 6 as shown in FIG. Also, screw the anchor bolt 4 into the female thread 3a of the anchor protrusion 3, connect it to the nearest reinforcement (not shown), and then attach it to the concrete.
)A is poured, and the embedding fitting main body 1 is embedded and fixed in this concrete ()A.

Next, after removing the formwork 6, insert the rod 10 such as a bar arrangement hanging fixture into the long hole 8a of the rod mounting plate 8, loosely tighten the nuts 12, and attach the mounting plate 8 to the embedded metal fitting body 1. Screw together.

When a pipe hanging fitting (not shown) is attached to the rod 10 to hang the pipe, if there is a misalignment between the buried position of the embedded fitting main body 1 and the pipe position, the rod mounting plate 8 is screwed and rotated.
At the same time, by sliding the rod 10 within the elongated hole 8a, the mounting position of the rod 10 can be easily adjusted within the range of the circle shown in imaginary lines in FIG.

After adjusting the rod 10 to a predetermined position in this manner, the nut 12 is tightened and fixed.

In order to prevent loosening due to vibration, etc., it is desirable to fill the embedded metal fitting body 1 with non-shrinkage mortar, etc., and finally, finish mortar is cast.

In addition, as a fixing method when embedding the embedding fitting main body 1 in the concrete (A) of the floor slab, the rod 10 is inserted into the long hole 8a.
The rod mounting plate 8 inserted through the is screwed onto the main body 1 in advance,
On the other hand, the main body 1 can also be positioned and fixed on the formwork 6 by making a through hole for the rod 10 in the formwork 6 and tightening the nuts 12 as shown in phantom lines in FIG.

In addition, by turning this embedded metal fitting upside down and embedding it in concrete on a balcony, it can also be used to fix fence posts.

Since the embedded fitting of this invention is as described above, the mounting position of the rod such as a pipe hanger can be easily adjusted.

Therefore, even if there is a misalignment between the buried position of the embedded fitting and the piping position, there is no need to forcibly bend the rod as in the past, which improves the efficiency of piping construction. Problems that could cause slab damage can also be eliminated.
